Sump Pump Runs Constantly, This is What the Plumber Says
We moved into this house last year, and have been doing water control maintainence on it ever since. The grade for drainage wasn't good, the gutters were ineffective, lots of cracks around the driveway and foundation of house - and since there were two sump pump failures that flooded the basement (with the previous owners), we put in a back up system. We've been fixing all the problems one by one.
This brings me to my situation/question:
One of the most recent upgrades we did was to put in a water powered back up sump pump. Along with this we put in a new "regular" sump pump, just "because". The old one was 4 years old, and we wanted the whole system to be new from here on. We noticed the new sump pump (Liberty brand) runs almost constantly. It comes on and ejects water every minute or two around the clock. We called the plumber back to take a look. While we were standing there at the sump pump, we could hear a constant flow of water going into the hole - which is why the sump pump runs constantly. (We knew the previous one ran a lot, but didn't notice if it ran as much as this one. This one is a little louder, so we hear it more). The plumber remarked to us, as he did when he did the original work, that there is water constantly flowing into the sump pump - "like someone's got a hose pointed into it", and that the sump pump is really just doing it's job. (The sump pump is in the below grade basement).
His idea is that we probably have a leak in a pipe between the street and the house that is flowing directly into the foundation tiles, into the sump pump, and then being ejected. This would be our responsibility to fix, not the city. We haven't noticed a water bill increase, which he says is b/c the leak is before the meter. He told us to check the water in the pump for chlorine. If there is any chlorine, then it's treated water, coming from a pipe from the city, leaking from a broken pipe in our front yard. So, we did the check, and there is like .05 chlorine. (We bought a chlorine check kit at Lowe's). My husband read online that .02 - .05 is the normal amount for chlorinated water.
I told my plumber that I've lived in neighborhoods all over this area for almost 30 years and never saw or heard of having to have front yard pipes replaced. He says his company does them all the time - every day, pretty much. (His company is big).
Is there another possible explanation for why the sump pump has constant water trickling into it, and why it registers as being chlorinated than there is a leaking pipe in the ground of our front yard?????
Any advice on how to be sure before we spend huge money having the yard dug up and pipes replaced??
